본 발명은 국산원목자원을 최대한 유효하게 이용하고 국내 목조건축에 적용할 수 있도록 강도등급, 제품규격 및 시공방법에 적합한 구조용 직교집성판상재의 제조방법 및 그와 같은 제조방법에 의해 제조되는 구조용 직교집성판상재에 관한 것이다.
The present invention relates to a method for producing a structural orthogonal laminated sheet material suitable for strength grade, product specification and construction method so as to utilize domestic timber resources as effectively as possible and to be applied to domestic wooden construction, and a method for producing structural orthogonally- Lt; / RTI >

금세기에 있어 가장 큰 문제인 지구온난화 방지를 위해 탄소저장이 가능한 건축구조재로 목재의 사용을 권장하고 있다. 우리나라에서도 국책사업으로 주거용 건축을 한옥으로 지정한 바 있다.In order to prevent global warming, which is the biggest problem in this century, wood is recommended as a structural material for carbon storage. Korea has also designated residential buildings as hanok with national projects.

또한, 한옥 등 중대형 목조건축물의 건축 증가율이 매년 20% 정도로 급성장하고 있다. 한옥용 목조건축부재는 다른 공법과 달리 기둥, 보 등 주요 구조부재를 대단면의 목재로 사용하게 되므로 국내산 목재 공급이 어렵고 소요량의 90%를 수입산 목재에 의존하고 있다.Also, the growth rate of middle and large sized wooden buildings such as hanok is rapidly growing to about 20% every year. Unlike other construction methods, the wooden structural members of Hanyok-in use large structural members such as pillars and beams, so it is difficult to supply domestic timber and relies on imported timber for 90% of the required amount.

한편, 구조용 직교집성판상재는 1990년대 스위스 등 EU지역에서 CLT(Cross Laminated Timber) 또는 Cross-Lam, X-Lam이란 명칭으로 개발되었으며 현재는 EU는 물론 미국, 일본, 호주, 뉴질랜드 등 국가에서 중대규모의 목재건축자재로 이용이 확대되고 있다.On the other hand, structural orthogonal lamellar plates were developed under the name of Cross Laminated Timber (CLT) or Cross-Lam and X-Lam in the EU region such as Switzerland in the 1990s. Currently, they are used in Europe, USA, Japan, Australia, The use of wood as a rebuilding material is expanding.

특히 대단면 판상재(板狀材)는 기둥, 보 등과 같은 축구조재(軸構造材)는 물론 주로 벽식구조의 벽체, 바닥 및 지붕재의 역할을 이 재료 한 종류로 활용할 수 있는 가장 큰 특징을 가지고 있어 장차 새로운 목질 구조재료가 될 가능성을 가진 목질판상재이다.Particularly, the large plate material has the greatest feature that can be used as a kind of this material as well as the role of walls, floors and roofs mainly of wall structure as well as soccer preparation materials such as pillars and beams It is a woody plate material that has the potential to become a new woody structural material in the future.

이와 같은 구조용 직교집성판상재는 치밀한 목재덩어리(뭉치)이며 강도성능을 확보하기 위하여 외층용재에는 높은 탄성계수를 가지는 층재로 구성된 평행겹층재를 배치하고 내층용재나 중간직교층에는 비교적 탄성계수가 낮은 직교겹층판재를 사용함으로써 고강도재료와 저강도 재료를 혼합사용할 수 있어 산림자원의 유효활용이란 관점에서 참으로 유용한 목질 재료라 할 수 있다.In order to secure the strength performance, the structural orthogonal lamellar members are arranged in parallel with each other. In order to secure the strength performance, a parallel laminated layer material composed of a layer material having a high elastic modulus is disposed in the outer layer material, By using the double-layered plate, it is possible to mix high-strength material and low-strength material, which is a useful wood material in terms of effective utilization of forest resources.

한편, 산림자원이 풍부하고 다양하며 대경재를 대량으로 생산할 수 있는 국가에서는 구조용 직교집성판상재의 기본소재인 층재를 제조하는데 최대두께 치수를 50㎜로 상한제한하고, 판상재의 폭은 600 ~ 3000 ㎜, 그리고 길이는 2 ~ 10m의 두껍고 넓으며, 긴 목질판상재를 만들 수 있지만, 우리나라에서 생산되는 산림자원은 소경재가 많고 수종도 제한적이며 결점이 많은 저강도 재료가 많아 세계적인 표준규격으로 제조하는 것은 불가능한 상태이다.On the other hand, in countries where forest resources are abundant and diverse, and large quantities of large diameter materials can be produced, the maximum thickness dimension is set at 50 mm for the production of the laminated material, which is the basic material of the structural orthogonal laminated sheet material, and the width of the plate material is 600 to 3000 mm , And 2 ~ 10m in length, it is possible to make a long woody plate material. However, since the forest resources produced in Korea have many blind materials, limited species, and many defective low-strength materials, It is impossible.

그러므로 우리나라에서 생산되는 원목자원에 적합하고 국내 목조건축에 적용할 수 있는 강도등급, 제품규격 및 시공성이 우수한 구조용 직교집성판상재의 제조방법의 개발이 필요하다.Therefore, it is necessary to develop a manufacturing method of structural orthogonal laminated sheet material which is suitable for the wood resource produced in Korea and is excellent in the strength grade, the product standard and the workability which can be applied to domestic wooden construction.

이와 같은 구조용 직교집성판상재와 유사한 기술로서 실용신안등록 제0334715호가 제안된 바 있다. 이는 겹층 집성판재에 관한 것으로, 소경재의 원목을 서로 목리가 교차하게, 표판층과 이판층을 포함하여 3층 이상 적층하되, 상기 표판층과 이판층은 원목 판재들을 그들의 폭 방향으로 2쪽 이상 부착하여 제조한다. 그러나 상기 겹층집성판재는 층재두께가 균일하고 강도성능을 보증할 수 없는 수장용이나 의장재로 사용되는 비구조재로 제조되고, 구조재 등을 사용하거나 마감용으로 사용하더라도 온도, 습도 또는 하중 등의 영향에 의해 내외층간의 박리 우려가 높아 구조재로 사용하기에는 적합하지 않다.A utility model registration No. 0334715 has been proposed as a technique similar to the above structure orthogonal plate. This laminate is composed of three or more layers of laminated wood of a small diameter material crossing each other and including a front plate layer and a two-layer plate, wherein the front plate layer and the two- . However, the above-mentioned laminated laminated sheet is made of a non-structural material which is uniform in thickness and can not guarantee the strength performance, and is used as a decorative material, and even if it is used for a structural material or the like, There is a high possibility of separation between inner and outer layers, which is not suitable for use as a structural material.

그러므로 목조건축 구조부재로 사용되는 주요한 원소재를 국산화하고 원목자원을 효율적으로 이용하기 위하여 정상재를 활용할 수 없는 간벌소경목재와 각재를 강도성능과 제품규격을 공학적 방법으로 개선해서 대단면의 한옥용 부재나 중대규모(中大規模)의 목재건축물 구축에 사용되는 목질구조 판넬(판상재(板狀材)) 생산이 시급히 필요한 실정이다.
Therefore, it is necessary to improve the strength performance and the product standard by the engineering method of the small size thin wood and timber which can not utilize the normal material in order to localize the main raw material used as the structural member of the wooden building and efficiently use the wood resource, It is urgently necessary to produce wood-structure panels (plate materials) used for building large-scale (large-scale) wooden buildings.

따라서 이와 같은 종래 기술의 문제점을 해결하기 위한 것으로서, 본 발명은 잔벌 등 소경원목에서 생산되어 정상재료로서는 사용할 수 없는 저강도 및 저질재료인 휨, 비틀림, 단척재, 결점재 등의 수심을 갖는 소경목재나 중단면 각재를 섬유방향이 서로 평행하게 폭 방향으로 병렬로 배열 접착하여 광폭의 내층용 직교겹층판재를 제조하고, 이 직교겹층판재의 표면과 이면에 필요에 따라 한 겹 또는 여러 겹의 외층용 평행겹층판재를 제조하여 내층용 직교겹층판재와 외층용 평행겹층판재의 섬유방향을 직교시켜 적층 접합시 결합력이 향상되는 판상(板狀)의 구조용 직교집성판재의 제조방법 및 그와 같은 제조방법에 의해 제조되는 구조용 직교집성판상재를 제공함에 있다.Accordingly, the present invention has been made to solve the problems of the prior art as described above, and it is an object of the present invention to provide a low-strength and low-quality small-diameter, low- The present invention relates to a method for producing a wide-width orthogonal laminated sheet for inner layer by arranging and bonding timber or interrupted plank sheets in parallel in the width direction parallel to each other in the fiber direction, A method of manufacturing a plate-shaped structural orthogonal plate material in which a parallel direction of the fiber direction of an inner layer-orthogonal two-layer plate material and an outer layer parallel laminate plate material is orthogonalized to improve a bonding force when the laminate is bonded, and a manufacturing method thereof And a structural orthogonal facet made of the same.

또한, 본 발명의 다른 목적은 목조건축의 벽식 구조공법에서 벽체 구조재, 바닥구조재 그리고 지붕구조재로 사용할 수 있으며 프래캐스트 콘크리트판(PCa) 구조물과 같이 강도성능이 우수하며 큰 하중을 받을 수 있어 조립식으로 시공할 수 있는 장점도 있어 중대규모(中大規模)의 다층 목조건축물의 구조부재로 사용할 수 있는 구조용 직교집성판상재의 제조방법 및 그와 같은 제조방법에 의해 제조되는 구조용 직교집성판상재를 제공함에 있다.
